the two devices Juan Carlos mentioned seem interesting (low price and available from many online-shops). However for a newbie in LMCE I don’t find it is straight forward to hook them up properly in LMCE and second to monitor and display consumption. I was checking a bit in the forum and found the following threats interesting:

Nevertheless, non of them is detailed enough to get me going. I have LMCE 810 final release, an Aeon labs stick S2, the Aeon Labs Home Energy Meter (two clamps), and the Everspring Switch Meter Plugin (AN158-2).

Tim, I saw that you where talking about a template for the Aeon Labs Home Energy Meter you where working on some time ago. Is it included in the final release of 810? Which number does it have?

I see, there is a lot of interest in energy monitoring and it would be great if someone could write (or point to) a little step by step guide, including:

1.) how to properly include the energy monitoring devices.2.) how to configure and pair them up.3.) how to display basic consumption data.
